Pornanong "Waen" Phatlum of Chaiyaphum won the LPGA Tour's Brazil Cup exhibition event Sunday, closing with a bogey-free 6-under 67 for a four-stroke victory over Taiwan's Amy Hung.

Pornanong "Waen" Phatlum lifts her trophy she won at the two-day Brazil Cup tournament at Rio de Janeiro.

It was the 22-year-old Thai's first win on the LPGA. She started on the premier tour last year.

"I'm so excited today," Pornanong said. "I played really well today and I played my own game. I'm just very happy. ... I very much liked coming to play here. Everybody was very nice. I love to play here. I will come back here."

Her brother, Pornpong, caddied for her.

"We just have fun today and my caddie, my brother, he helped me to concentrate," Pornanong said. "He helped me to focus on my game and kept me in the round."

When she joined the US-based LPGA tour last year, Pornnanong said her goal in life was to be one of the Top 10 players," and she will need more wins to match the achievements of her golfing idol, Lorena Ochoa.

She began playing at 9, and credits her father as the leading influence in her golf life. She says shopping is her favourite hobby, and the $108,000 (3.3 million baht) she won in Brazil will help with that.

Pornanong finished at 13-under 133 in the two-day, 30-player tournament at Itanhanga Golf Club. She had five birdies on the front nine to pull away.

The toughest part of the victory was that greens. "That, and it's a very narrow golf course," she said. "I just have to concentrate on my target."

Hung made nine birdies and a bogey for a 65, the lowest round at the event.

Paula Creamer eagled the par-five ninth hole, but had two bogeys on the back nine to shoot a 69 for a share of third place with Chella Choi at eight-under.

Pornanong entered the final round of the unofficial event tied for the lead with Karine Icher at 7-under-par. She got off to a hot start on Sunday with five birdies on the front nine en route to running away with the tournament. Phatlum becomes the fourth different champion of the HSBC LPGA Brasil Cup following Mariajo Uribe in 2011, Meaghan Francella’s win in 2010 and Catriona Matthew in 2009.
